Hmm...it looks like the gateway is communicating to some SIP proxy/server and complaining that either To/From headers in one of the messages is wrong

you might want to take a look at a 'debug ccsip messages' or 'debug ccsip all' for this. We need to look at the INVITE message and see what the GW is complaining about, and if it's a correct complaint or not

if the GW is up to code, it might be that the server may be sending a non rfc compliant INVITE request

The second set of messages you provided are normal and don't indicate any problems
